Scale — Personal (P) to Titan (T)

No Outside Book Needed Star Wars has humans, speeder bikes, walkers, starfighters, and Star Destroyers. They don't fight on the same math. A Jedi with a lightsaber can't cut a Star Destroyer's bridge in half. A Star Destroyer can't snipe a Jawa on a speeder bike. Scale makes that true in the rules.

The Six Scales

Scale	Tag	What Lives Here	Typical Defense Penalty (already in statblock)	Typical Toughness	Typical Damage
0 Personal	P	Human, Jawa, Wookiee, droid, Ewok	+2 Small / -1 Large (Ewok harder to hit than Wookiee)	0-8 (NAT + Armor)	2-8 (hold-out 3, blaster pistol 4, rifle 6, lightsaber 8, rocket 10)
1 Ground Vehicle	V	Speeder bike, landspeeder, airspeeder, swoop	-0 to -2 Handling	8-10	6-10 (light cannon 6, heavy repeating 8)
2 Heavy Ground / Walker	W	AT-ST (9m), AT-AT (22m), Occupier tank, AAT	-2 to -6 Handling (AT-ST -2, AT-AT -6)	11-15	10-14 (AT-ST blaster 9, AT-AT heavy laser 12)
3 Starfighter	S	TIE, X-wing (12m), Y-wing, YT-1300 (35m), Firespray	-2 to -4 (X-wing -2, YT-1300 -4)	9-13 + Shields 6-10	8-13 (laser 8, ion 8 Affliction, concussion 10 Burst, proton torp 12)
4 Capital	C	CR90 (150m), Raider (150m), Nebulon-B (300m), Victory (900m), ISD (1600m)	-8 to -16	13-18 + Shields 11-15	13-18 (turbolaser 13 Inaccurate, heavy 15)
5 Titan	T	Executor (19km), Death Star (160km), Torpedo Sphere, station — not player scale	-20+	20-25 + Shields 15-20 Impervious	18-25 (superlaser 25)

Rule of thumb: P < V < W < S < C < T. If you remember that line, you know scale.

Size Inside Scale Still Matters

Scale does NOT erase size differences inside the scale. A Wookiee and a Jawa are both P, but a Jawa is 15% harder to hit.

Who	Size	Speed	Dodge / Parry vs P attackers	Stealth	Intimidation	Carry
Gozzo, Jawa	Small	5m	+2 (hard to hit)	+4	-2	(STR+5)×10kg -5kg
Human, Rodian, Bothan, Tusken	Medium	7m	+0 (baseline)	+0	+0	(STR+5)×10kg
Wookiee, Trandoshan tall	Large (or Powerful Build)	7m	-1 (easier to hit) if Growth 2, or +0 if Powerful Build variant	-2	+1	(STR+5+2)×10kg

In Sins we use: Small = Speed 5m, +2 Dodge, +2 Parry, +4 Stealth, -2 Intimidate. Medium = 7m +0. Large = 7m -1 Dodge, -1 Parry, -2 Stealth, +1 Intimidate, Powerful Build for carry (you choose variant at species). Sheet applies it automatically. Same applies to vehicles: X-wing (12m, Huge) is Defense -2 Handling, YT-1300 (35m, Gargantuan) is -4. Inside the same scale, bigger = easier to hit.

Shooting UP — Small Guns vs Big Targets

• To-hit: +0 from Scale. The target's Size is already in its Defense (big = easy). Don't add extra.
• Damage: -5 per Scale step UP. Your gun loses 5 Damage ranks for each step you shoot up. If Damage after penalty ≤0, don't roll — narration only.
• Also +5 Impervious Toughness per step on the target's side. If you beat Impervious but still do damage, use normal Toughness +5 per step.

Examples:

• Blaster pistol Dmg4 (DC19) vs AT-ST (W). P(0)→W(2) = 2 steps up = -10 Damage = Dmg -6 = DC9. AT-ST Tough13. No roll. "Your bolts ping off its leg armor."
• Blaster rifle Dmg6 vs same AT-ST = Dmg6-10 = Dmg -4 = no effect.
• Missile Launcher Dmg10 Heavy vs AT-ST. Heavy ignores 1 step up → only -5 = Dmg5 (DC20) vs Tough13 → needs 7+ on Toughness. It hurts.
• Proton Torpedo Dmg12 (S) vs Victory (C). S(3)→C(4) = 1 step up = -5 = Dmg7. But torpedo is Heavy → ignores that step → full Dmg12 vs Victory Tough16+Shields — needs a good hit.

Heavy weapons (ignore 1 Scale step UP): Missile launcher, proton cannon, proton torpedo, concussion missile, AT-scale rifle (E-Web), thermal detonator (thrown), vehicle-mounted heavy lasers.

Shooting DOWN — Big Guns vs Small Targets

• To-hit: -5 per Scale step DOWN. Big guns are made to hit big targets, not Jawas.
• Damage: +5 per Scale step DOWN. If it hits, it vaporizes.
• Additional -5 to-hit if target did Evasive Maneuvers (Pilot Vehicle check).

Examples:

• AT-ST W(2) vs human P(0): 2 steps down = -10 to-hit, +10 Damage. AT-ST Dmg9 +10 = Dmg19 (DC34) — human Tough4+Prot3=7 rolls DC34 = needs 27+ = dead if it hits, but -10 to-hit means it rarely hits an aware human in cover.
• Same AT-ST vs Jawa Small (+2 Dodge): AT-ST -10 to-hit, Jawa +2 Dodge = -12 total. Jawa is 15% harder to hit than a Wookiee Large (-1 Dodge → -9 total for Wookiee). That's the 15% swing players feel.
• YT-1300 S(3) vs Speederbike V(1): 2 steps down = -10 to-hit +10 Damage, but YT's dorsal turret is Point-Defense → ignores 1 step of to-hit penalty → only -5 to-hit.

Point-Defense weapons (ignore 1 Scale step DOWN to-hit): Anti-infantry lasers on AT-ST, AT-AT side cheek guns, starfighter defensive turrets, capital point-defense batteries.

Quick Table — Cross-Scale Modifiers

Attacker → Defender	Steps	To-hit	Damage	Then add target's Size
P → V	1 up	+0	-5	V is Large-ish -1 to -2 Def = easier
P → W	2 up	+0	-10	W is Huge -4 Def = easier
P → S	3 up	+0	-15 → always 0	Don't shoot your pistol at an X-wing
V → W	1 up	+0	-5	Speeder heavy blaster vs AT-ST needs Heavy to matter
W → P	2 down	-10	+10	+2 vs Jawa, -1 vs Wookiee
S → P	3 down	-15	+15	Starfighter vs infantry is -15 to-hit — use Point-Defense
S → C	1 up	+0	-5 (Heavy ignores)	C is Colossal -10 Def
C → S	1 down	-5	+5	S is Huge -2

What The Sheet Does

• Size dropdown applies +2 Dodge/Parry for Small, -1 for Large automatically.
• Scale dropdown on attacker applies -5 Damage per step UP, -5 to-hit / +5 Damage per step DOWN automatically.
• If Damage after penalty ≤0, sheet shows "No Effect — narration only".
• Heavy checkbox ignores 1 step up. Point-Defense checkbox ignores 1 step down to-hit.

Common Questions

Can a lightsaber hurt an AT-ST? Lightsaber Dmg8. P(0)→W(2)=2 up = -10 = Dmg -2 → no. Even with Improved Crit it's no. You need to be inside it (breach) or use Heavy (not lightsaber). That's intentional — Luke doesn't saber AT-AT legs, he trips them.

Can my Z-95 shoot a guy? S→P = 3 down = -15 to-hit, +15 Damage. Z-95 lasers Dmg7+15=Dmg22 DC37 vs human Tough6 → vapor if hits, but -15 to-hit means you need Point-Defense mode or strafe. Point-Defense ignores 1 step → -10 to-hit, still hard. That's why fighters strafe with Evasive targets at -5 more = -15. Use missiles (Burst) or let the AT-ST handle infantry.

Do shields help vs scale? Yes. Shields are Toughness. Starfighter Shields 8 means Tough11+Shields8=19 vs P pistol Dmg4-15=-11 = no. Proton torpedo Heavy ignores 1 step so it actually stresses shields.
